How does the strong nuclear force hold the nucleus of an atom together?

a) It overcomes the electrical force of attraction between protons in the nucleus. b) It overcomes the electrical force of repulsion between protons in the nucleus. c) It overcomes the electrical force of repulsion between electrons in the nucleus.

The strong nuclear force holds the nucleus of an atom together.

Somehow, it overcomes the electrical force of repulsion between protons in the nucleus, which all have the same charge but still stay close together somehow. (b)

Answer: Option (b) is the correct answer.

Explanation:

An atom consists of three sub-atomic particles that is, protons, neutrons and electrons.

Protons are positively charged, neutrons have no charge and electrons are negatively charged.

Both protons and neutrons are present inside the nucleus and electrons revolve around the nucleus. Due to like charges of protons there occur electrostatic forces of repulsion which are overcome by a strong nuclear force that is known as binding energy.

Hence, we can conclude that the strong nuclear force hold the nucleus of an atom together as it overcomes the electrical force of repulsion between protons in the nucleus.
